We aren't even close to that yet. The argument is an appeal to novelty, fallacy of progress, linear thinking, etc.

LLMs aren't solving NLU. They are mimicking a solution. They definitely aren't solving artificial general intelligence.

They are good language generators, okay search engines, and good pattern matchers (enabled by previous art).

Language by itself isn't intelligence. However, plenty of language exists that can be analyzed and reconstructed in patterns to mimic intelligence (utilizing the original agents' own intelligence (centuries of human authors) and the filter agents' own intelligence (decades of human sentiment on good vs bad takes)).

Multimodality only takes you so far, and you need a lot of "modes" to disguise your pattern matcher as an intelligent agent.

But be impressed! Let the people getting rich off of you being impressed massage you into believing the future holds things it may not.
